EXTREMELY LOW TEMPERATURES! - Using TECs

I explain why stacking TECs is not done to increase their cooling efficiency, but can be used to achieve very low temperatures.

Construction and testing of the freezer is coming up in the next video. Stay tuned!

Thanks for watching!

the true value of Youtube right here...

[DangerDarin]

These guys are an intellectual oasis in the sometimes abysmal (king of random) world of YouTube. Thanks for the content.

[dorianmccarthy]

I was enjoying the video then saw the -56 degrees C temperature - holy moly! nice work!

[ancienttechnology]

I can't believe it's been 5 years. Incredibly valid content at the moment.

[Lukegear]

Always good to watch a Tech Ingredients video :)

[gibbyrockerhunter]

A very amazing clarification for myself. Thank you. I will work on my patients for more info. I really could have used this video back in January. Then again, afterwards it is always gratifying to know you learned from your own R an D. To have you confirm everything, makes it that much sweeter.

2:50 ackshually, it's not a 12-710, it's more of a 127-10 (127 elements, 10A rated current)

Thanks for this. I know this is now an old video but i've been trying to find info on cooling a volume of air inside a box (camera inside it) with TEC's and this series (especially this video) is so useful in understanding what im trying to figure out to get this done effectively

I experimented with TEC 20 years ago (From MECI if anyone remembers) and found the same inefficiencies from stacking. Also, they are much better heaters than coolers. Create 46w heat vs 18w cooling. Great video as always.

[JakeHarris]

Very good explanation. Thank you!
Do be careful using glycol with PC cooling parts as they often contain PVC that will react with the glycol.

These TEC elements typically have a maximum COP when operating around 2V with a dT of 10K, however, you need a lot of them at such low voltages to get the job done! Their COP also increases a lot with increasing T(hot), ceteris paribus.

Sweet jeezeus, I'm so happy I found this video! I started playing around with peltier modules recently with a complete simpleton's understanding since I put zero due diligence into *first* educating myself, only to presented with what are basically engineering PhD dissertations as far as figuring out how to use these gizmos.... First youtube video I've found that's doing hardcore, ridiculously over-my-head things with them & also giving advanced practical advice from a highly informed standpoint. Thank you!

[prabhacar]

I would love to be able to explain concepts with the clarity that you have in your videos. Excellent and inspiring!

[CiscoSaeed]

All your videos related to TEC is really amazing and I thought a lot from your ! Thanks a lot Sir!

[WhoLocke]

This is golden, thank you for the maths! Your presentation reminds me of a good lecture that gets me stoked on whatever you're talking about.

[WhatDennisDoes]

Ahh, the inefficiency builds in series...of course. This is something I've always wanted to put together so thanks for the demonstration!

[anarchangel]

We apparently have many random interests in common. Love the content. Thank you!

this is my new favorite youtube channel

[jameshicks]

This is very helpful. I am planning a cloud chamber project, and I want to build one with a larger, top-down viewing area approximately 8 inches square. Ideally, I'd like to consistently get the cold plate below -30 C in a + 22-24C room, and have it operational for at least 30 minutes at a time.

It is said that only those who can explain the apparently complex in simple terms actually understand what they are talking about. This guy is one of the few (not very many) on YouTube who ACTUALLY understand what they are presenting to us. Would that there was more material of this quality. No fuss, no messing about, just clarity and explanation of whatever he is doing this time.
